Client Package
The client package takes care of query and broadcast operations towards a cosmos-sdk based chain (updated to stargate).
Chain Client
pub struct ChainClient {
pub node_info: NodeInfo,
pub grpc_addr: String,
pub lcd_addr: String,
}
pub struct NodeInfo {
pub id: String,
pub network: String,
}
Get Account data
fn get_account_data_example() {
let grpc_endpoint = "http://localhost:9090";
let lcd_endpoint = "http://localhost:1317";
let address = "desmos1rc4jrjyxyq0qpv7sn5ex9tr0kt0chrdq3x66ah";
let node_info = get_node_info(lcd_endpoint.to_string())
.await
.unwrap()
.node_info;
let chain_client = ChainClient::new(
node_info,
lcd_endpoint.to_string(),
grpc_endpoint.to_string(),
);
let account = chain_client.get_account_data(address.to_string()).await.unwrap();
}
Broadcast transaction
fn broadcast_tx_example() {
let wallet = Wallet::from_mnemonic(...).unwrap();
let chain_client = ChainClient::new(...);
let msg = MsgSend {...};
let fee = Fee {...};
let mut msg_bytes = Vec::new();
prost::Message::encode(&msg, &mut msg_bytes).unwrap();
let proto_msg = Msg(Any {
type_url: "/cosmos.bank.v1beta1.Msg/Send".to_string(),
value: msg_bytes,
});
let msgs = vec![proto_msg];
let account = chain_client
.get_account_data(wallet.bech32_address.clone())
.await
.unwrap();
let tx_signed_bytes = wallet
.sign_tx(
account,
chain_client.node_info.network.clone(),
msgs,
fee,
None,
0,
)
.unwrap();
let transaction_response = chain_client
.broadcast_tx(tx_signed_bytes, BroadcastMode::Block)
.await
.unwrap();
}
